NAME

ANTLR - ANother Tool for Language Recognition, version 3

SYNOPSIS

antlr3 [args] file.g [ file2.g file3.g ...]

DESCRIPTION

ANTLR (ANother Tool for Language Recognition) is a parser generator for reading, processing, executing, or translating structured text or binary files. It's widely used to build languages, tools, and frameworks. From a grammar, ANTLR generates a parser that can build and walk parse trees.

-o outputDir

specify output directory where all output generated.

-fo outputDir

same as -o but force even files with relative paths to dir.

-lib dir

specify location of token files.

-depend

generate file dependencies.

-report

print out a report about the grammar(s) processed.

-print

print out the grammar without actions.

-debug

generate a parser that emits debugging events.

-profile

generate a parser that computes profiling information.

-trace

generate a recognizer that traces rule entry/exit.

-nfa

generate an NFA for each rule.

-dfa

generate a DFA for each decision point.

-message-format name

specify output style for messages.

-verbose

generate ANTLR version and other information.

-make

only build if generated files older than grammar.

-version

print the version of ANTLR and exit.

-language L

override language grammar option; generate L

-X

display the list of extended arguments

-Xgrtree

print the grammar AST

-Xdfa

print DFA as text

-Xnoprune

test lookahead against EBNF block exit branches

-Xnocollapse

collapse incident edges into DFA states

-Xdbgconversion

dump lots of info during NFA conversion

-Xconversiontimeout

use to restrict NFA conversion exponentiality

-Xmultithreaded

run the analysis in 2 threads

-Xnomergestopstates

do not merge stop states

-Xdfaverbose

generate DFA states in DOT with NFA configs

-Xwatchconversion

print a message for each NFA before converting

-XdbgST

put tags at start/stop of all templates in output

-Xnfastates

for nondeterminisms, list NFA states for each path

-Xm m

max number of rule invocations during conversion [4]

-Xmaxdfaedges m

max "comfortable" number of edges for single DFA state [65534]

-Xmaxinlinedfastates m

max DFA states before table used rather than inlining [60]

-Xmaxswitchcaselabels m

don't generate switch() statements for dfas bigger than m [300]

-Xminswitchalts m

don't generate switch() statements for dfas smaller than m [3]

-Xsavelexer

don't delete temporary lexers generated from combined grammars
